BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petuniaplant, botanically known as (Petunia×hybrida)×Calibrachoa sp. andhereinafter referred to by the name ‘Duesunpur’.

The new Petunia plant is a product of a planned breeding programconducted by the Inventor in Encinitas, Calif. The objective of thebreeding program is to create new moderately vigorous and trailingPetunia plants with numerous attractive flowers.

The new Petunia plant is a naturally-occurring whole plant mutation of aproprietary selection of (Petunia×hybrida)×Calibrachoa sp. identified ascode number TT-0806, not patented. The new Petunia plant was discoveredand selected by the Inventor as a single flowering plant within apopulation of plants of the parent selection in a controlled greenhouseenvironment in Encinitas, Calif. on Nov. 11, 2015.

Asexual reproduction of the new Petunia plant by terminal vegetativecuttings in a controlled greenhouse environment in Encinitas, Calif.since Nov. 12, 2015 has shown that the unique features of this newPetunia plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duesunpur’. These characteristics incombination distinguish ‘Duesunpur’ as a new and distinct Petunia plant:

-   -   1. Mounding to outwardly trailing plant habit.    -   2. Moderately vigorous growth habit.    -   3. Freely branching habit.    -   4. Early and freely flowering habit.    -   5. Medium to large-size flowers with dark red purple-colored        petals with greyed and dark purple-colored centers and venation.    -   6. Good garden performance.

Plants of the new Petunia can be compared to plants of the parentselection. Plants of the new Petunia differ primarily from plants of theparent selection in flower color as plants of the parent selection havelight violet-colored flowers.

Plants of the new Petunia can be compared to plants of(Petunia×hybrida)×Calibrachoa sp. ‘Duesunblsk’, disclosed in a U.S.Plant patent application Ser. No. 15/530,210. Plants of the new Petuniadiffer primarily from plants of ‘Duesunblsk’ in flower color as plantsof ‘Duesunblsk’ have dark violet-colored flowers. In addition, plants ofthe new Petunia have slightly larger flowers than plants of‘Duesunblsk’.

Plants of the new Petunia can be compared to plants ofPetunia×Calibrachoa ‘Dancalipet’, disclosed in U.S. Plant Pat. No.16,063. Plants of the new Petunia and ‘Dancalipet’ differ primarily inthe following characteristics:

-   -   1. Plants of the new Petunia are more trailing than and not as        mounding as plants of ‘Dancalipet’.    -   2. Plants of the new Petunia are more vigorous than plants of        ‘Dancalipet’.    -   3. Plants of the new Petunia have larger flowers than plants of        ‘Dancalipet’.    -   4. Plants of the new Petunia and ‘Dancalipet’ differ in flower        color as plants of ‘Dancalipet’ have lighter red purple-colored        flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurementsand values describe plants grown during the early autumn in summer in15-cm containers in a polyethylene-covered greenhouse in Encinitas,Calif. and under cultural practices typical of commercial Petuniaproduction. During the production of the plants, day temperaturesaveraged 26° C., night temperatures averaged 17° C. and light levelsaveraged 4,500 lux. Plants were pinched one time at planting and wereseven weeks old when the photographs and description were taken. In thefollowing description, color references are made to The RoyalHorticultural Society Colour Chart, 2007 Edition, except where generalterms of ordinary dictionary significance are used.
